Join the FIELD GUIDE crew on a three-day journey deep into the Eagle Cap Wilderness in search of a truly ancient tree. Discovered recently on a dangerously steep slope in the Wallowa Mountains, it could be among the oldest trees in Oregon – and it’s still alive. Tune in to the stations of Oregon Public Broadcasting on Thursday, June 3 at 8:30pm. Also a look at the impact of ethanol on boat engines and how forest surveyors do their jobs.

Ancient Tree - An avid hiker discovered a gnarled limber pine on one of his backpacking adventures several years ago. Fascinated by the prospect it could be thousands of years old, he invited FIELD GUIDE along on an arduous trek to visit the monarch. Accompanied by several experts who would take core samples to try and determine the tree’s age, they scramble up a 2,000-foot slope where they find the squat giant clinging to a bed of limestone. All agree it’s a humbling experience to be in the presence of a living thing that grew on these slopes even before the time of Genghis Khan.

Ethanol - On the Columbia River, boat engine trouble can be fatal. Clogged fuel lines seem to be more common than fish these days and boat owners point to gasoline containing ethanol as the culprit. The fuel is especially hard on boat engines. It eats through hoses and clogs fuel lines. There are some measures that can be taken and now the Oregon legislature is stepping in to ease some fuel requirements.

Forest Surveyors - Every square mile of Oregon has been walked, staked and surveyed at one time. The original land surveyors passed through in the 1850’s on pack mules and stayed out for months at a time. You’d think today’s surveyors would have it easier, but this is still a tough job that requires a love of bushwacking and exceptional navigation skills.
